Because of regular rocket attacks on its territory, Israel has been conducting military incursions into Gaza, including an artillery shelling that killed 19 civilians. In response to the attack, Palestinian militants fired even more rockets into Israel, killing a woman and prompting Defense Minister Amir Peretz to vow revenge.
Israeli Defence Minister Amir Peretz has said Palestinian militants will pay a heavy price for a rocket attack which killed an Israeli woman.
Militants from the armed wing of the governing Hamas movement and Islamic Jihad said they had fired the rockets into the Israeli town of Sderot.
Israel has been carrying out raids in Gaza intended to stop such attacks.
In Geneva, the U.N. condemned Israel for an artillery strike in Gaza last week, which killed 19 Palestinian civilians.
In a special session, the U.N. Human Rights Council voted to send a fact-finding mission to the scene of the off-course strike, the town of Beit Hanoun.
An Israeli military investigation has blamed technical failures for the deaths.
